What game will be Switch's first 3 million seller in Japan at retail?

Unless Pokemon is actually ready to go for this year, it'll be between either Splatoon 2 or Animal Crossing. But, that's assuming Animal Crossing is announced and released this year. It only took 'New Leaf' 10 weeks to reach the numbers that Splatoon 2 are at now as of This Update. And if it releases in the Holiday Season it'll take even less time than that!
If it DOES get announced and released this year, it'll be a close two horse race between them. If not, than Splatoon 2, easily.
